Liquid crystal display device

A liquid crystal display device having a reflective liquid crystal display element, the reflective liquid crystal display element comprising:

• a set of substrates having an electrode to apply a voltage to a liquid crystal layer;
• a twisted liquid crystal layer interposed between the substrates;
• an elliptic polarizer consisting of a polarizer, a first retarder, and a second retarder having a slow axis substantially parallel to a bisector of alignment directions of liquid crystal material at substrate interfaces, and producing retardation of less than 140 nm;
• and
• a reflector reflecting light in a visible light range;
• wherein a product (nm) of birefringence Δn of liquid crystal material used in the liquid crystal layer and a thickness d of the liquid crystal layer is not less than 120 nm, and not more than a value given by Formula 1:
• Formula 1:
• ⁢ 89.2 + 1.42 × 10 6 [ Re + ( Re ′ - 270 ) · cos ⁡ ( 2 ⁢ [LeftBracketingBar] α 3 - α 2 [RightBracketingBar] ) ] 2
• when a twist angle in the liquid crystal layer is in a range of 63 to 77 degrees, an angle between a transmission axis α1 of the polarizer and a slow axis α2 of the first retarder is in a range of 5 to 25 degrees or in a range of 95 to 115 degrees, an angle between the slow axis α2 of the first retarder and a slow axis α3 of the second retarder is in a range of 50 to 70 degrees, retardation produced by the second retarder is Re (nm), and retardation produced by the first retarder is Re′ (nm).
